The DNA tests are fine, the interpreting for "ethnicity" is dodgy and different for each company as their databases differ.
What is not in question is the ability to match DNA for families whose members are tested. In what amounts to thousands of blind trials family members who did not know their cousin/brother/sister had the test got a resultant match when their results were returned.
